Detailed ways

Embodiment 1: As shown in accompanying drawings 1 to 5, a baby stroller includes a stroller frame 1 with an unfolded position and a folded position, and multiple sets of wheels arranged at the bottom of the stroller frame 1 components, a locking mechanism for locking the stroller frame 1 in the unfolded position, a seat arranged on the stroller frame 1, and the baby stroller also includes a The auxiliary seat 6 at the rear of the trolley frame 1, the auxiliary seat 6 includes an auxiliary seat frame 7, and the auxiliary seat frame 7 is provided with at least one group of auxiliary seats for supporting the auxiliary seat 6 As for the wheel assembly 11, there is only one set of auxiliary wheel assemblies 11 in this embodiment, but two or three sets of auxiliary wheel assemblies are all possible. Seats and auxiliary seats are usually provided with seat cloth covers

The auxiliary seat 6 is detachably connected to the rear part of the stroller frame 1 . Thereby, switching between the single-seat baby stroller and the double-seat baby stroller can be realized.

The cart frame 1 includes a left rear wheel bracket 2 on the left side, a right rear wheel bracket 3 on the right side, and multiple sets of the wheel assemblies include a rear wheel assembly located at the rear of the cart frame 1. The left rear wheel assembly 4 and the right rear wheel assembly 5, the left rear wheel assembly 4 is arranged on the left rear wheel support 2, and the right rear wheel assembly 5 is arranged on the right rear wheel support 3, the auxiliary seat 6 also includes a left auxiliary seat connecting frame 8 and a right auxiliary seat connecting frame 9 respectively fixedly connected to the left and right sides of the seat frame, and the left auxiliary seat connecting frame 8 and The corresponding left rear wheel bracket 2 is connected, and the right auxiliary seat connecting frame 9 is connected with the corresponding right rear wheel bracket 3 . The left sub-seat connecting frame 8 is detachably connected to the corresponding left rear wheel bracket 2, and the right sub-seat connecting frame 9 is detachably connected to the corresponding right rear wheel bracket 3. connect. That is to say, in this embodiment, the auxiliary seat 6 and the stroller frame 1 are connected together through two connection structures, that is, the left auxiliary seat connecting frame 8 and the right auxiliary seat connecting frame 9 . Under the premise of ensuring the rigidity after connection, only one phase connection is also possible. And, the connection structure between the left auxiliary seat connecting frame 8 and the left rear wheel support 2, the detachable connection structure between the right auxiliary seat connecting frame 9 and the right rear wheel support 3 are not the gist of the present invention. As long as it can connect and fix two separable parts, it is all possible. Such as screw and bolt connection, it can also be provided with a lock portion on the left rear wheel bracket 2, and a lock hook is slid or rotated on the left auxiliary seat connecting frame 8, which is realized by hooking the lock hook to the lock groove. Connect between the left auxiliary seat connecting frame 8 and the left rear wheel bracket 2.

The auxiliary seat 6 also includes an auxiliary seat back frame 10 arranged on the auxiliary seat frame 7 .

The second embodiment, the difference between the second embodiment and the first embodiment is that the structure of the cart frame 1 is different, and the folding principle is different, as shown in Figure 6 . And the auxiliary seat 6 does not constitute the necessary connecting rod of the cart frame 1 in the process of unfolding and folding, so the auxiliary seat 6 can be installed on the cart frame 1 of various folding principles.

As mentioned above, we have fully described according to the purpose of the present invention, but the present invention is not limited to the above-mentioned embodiments and implementation methods. Practitioners in the relevant technical fields may make various changes and implementations within the scope permitted by the technical ideas of the present invention.
